The mean of a sequence of n numbers is m. If we split the sequence into two sequences of lengths n1 and n2 and compute their mea
Furkat [3]

The mean of a sequence of numbers is the average.

The true statement is: \mathbf{mn = m_1 \times n_1 + m_2 \times n_2}

The given parameters are:

\mathbf{Mean = m}

\mathbf{Size = n}

The mean of a dataset is calculated as:

\mathbf{Mean = \frac{\sum x}{Size}}

So, we have:

\mathbf{m = \frac{\sum x}{n}}

Multiply both sides by m

\mathbf{\sum x = mn}

When the sequence is split into two, we have:

\mathbf{\sum x_1 = m_1\times n_1}

\mathbf{\sum x_2 = m_2\times n_2}

Where:

\mathbf{\sum x_ = \sum x_1 + \sum x_2}

So, we have:

\mathbf{mn = m_1 \times n_1 + m_2 \times n_2}

Hence, the true statement is: \mathbf{mn = m_1 \times n_1 + m_2 \times n_2}

What is the x-intercept of the equation 7x + 3y = 21?<br> (0, 3)<br> (0, 7)<br> (3, 0)<br> (7, 0)
notka56 [123]

Answer:

(3, 0)

Step-by-step explanation:

we have

7x+3y=21

we know that

The x-intercept is the value of x when the value of y is equal to zero

so

For y=0

substitute in the equation and solve for x

7x+3(0)=21

7x=21

Divide by 7 both sides

x=3

therefore

The x-intercept is the point (3,0)

TanA × cosecA = secA​
Rashid [163]

Step-by-step explanation:

L.H.S

tanA * cosecA

=sinA/cosA * 1/sinA

now cancel sinA and sinA

then,

1/cosA

= secA

= RHS

hence proved
